MyDateTime.Date will return a new object with the time element reset to midnight.
|
|
|
|
|
you can also format the date
Datetime datetime=Person.subscribedate;
datetime.tostring("d");
|
|
|
|
|
you should return only date from sql
you can use convert function
forexample
convert(datecolumn,varchar,101)
it'll only return date not time

Hi,
System.ComponentModel.Design.IReferenceService.GetComponent() is described by MS here:
http://msdn2.microsoft.com/en-us/library/system.componentmodel.design.ireferenceservice.getcomponent.aspx
unfortunately the do not offer example code.
This is what I know:
If a component is sited, you can get the IReferenceService by a call of Site.GetService()...
this works fine.
My Problem:
with C# Express at DesignTime, I always get:
Parent.Equals(myComponent) == true
as a result of this kind of code:
Component myComponent;<br />
IReferenceService refSvc;<br />
[...].br />
IComponent Parent = refSvc.GetComponent(myComponent);<br />
Am I doing something wrong, or is this a bug?
best regards,
Bernd

no one knows?
no ideas?
Am I describing anything unclear?
This is about writing a custom UITypeEditor for replacing the buildin one for a property like this:
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]<br />
public Component Owner<br />
{<br />
get { return this._Owner; }<br />
set { this._Owner = value; }<br />
}
The build in Editor allows choosing components from a toolbox, which are private Fields in the BaseClass of my Form. The result is, that the code added by the designer cannot be compiled anymore, if such a component is chosen.
I am also experimenting with IInheritanceService and IDesignerHost to solve this... I already have a DropDown Editor that works, but till now I cannot filter the shown components properly...
Normal Reflection is no help here, as Reflection does not work on the RootComponent of the Designer...
... I'll check if TypeDescriptor solves the Reflection lack...
So the complete Problem I have to deal with:
How to find out if a Component in DesignMode is a field of the Designers RootComponent or a public or protected (but not private) field of the RootComponents base class...
best regards,
Bernd

I solved the complete Problem, but without IReferenceService.GetComponent()...
... would still be interresting if anyone knows about this...
My solution:
Get the RootComponent with IDesignerHost
Check if the Component you want to use is a Field of the RootComponent by using Reflection:
FieldInfo FI = RootComponent.GetType().GetField(ComponentName, BindingAttributes...);
-> as Reflection on the RootComponent itself is not possible, you will only get Results for Fields of a BaseType
-> you can get also private fields of the BaseType (The code needs ReflectionPermission!)
-> you can be (almost) sure, that all Components for which you cannot find fields, are Components with fields in the RootComponent.
-> all Components with fields in the RootComponent are accessible
-> all private fields you got by reflection are not accessible
best regards,
Bernd

Hi,
How to make a button transparent?
|
|
|
|
|
Set the Opacity property to something less than 100%
|
|
|
|
|
Button does not ve a opacity property as far of my knowledge
|
|
|
|
|
Button control provides the opacity function ???????????????????
|
|
|
|
|

Hi,
I have tested it here, and its working fine.
See I have done the Following to test :
I have created Form as "Form1" and a button as "button1" over it.
Form1.BackgroundImage = TransparentButton.Resource1.Image2;
This just to check if transparentcy is working.
For the Button too I have used a Bitmap.
button1.Image = TransparentButton.Resource1.Image1;
Now in the Constructor of the Form I have set:
button1.BackColor = Color.Transparent;
Also, please set the
FlatStyle as "Popup" for the "button1".
That makes the button transparent, meaning u can see the Image2 from over the
button body.

hi,
Thanks. I don't need any images both on button and form. My idea is to place the button dynamically on the datagrid and when dragged it should be transparent. Hope u got my point
Bye

|

hi,
if you are using .net v1.1 then you have to set the backcolor of the button to Color.Transparent.
like:
this.button1.BackColor = System.Drawing.Color.Transparent;
and FlatStyle should NOT be "System.Windows.Forms.FlatStyle.System"
It can be either Flat, Popup, or Standard; but NOT System

{
class WordPair
{
string[] rightpair = new string[] {"below\tunter", "blue\tgel", "cat\tgelb", "cat\tdie Katze",
"red\trot","the dog\tder Hund","to read\tlesen"};
string [] wrongpair = new string []{"below\trot", "bue\tlesen", "cat\tunter", "red\tgelb",
"the dog\tdie katze"};
}
}
I am a beginner in C# programming and seeking advice.
What I am trying to do here is to build up an application in 4 parts.
Part A.
Which I have already started with the code above, to be an application that has the class WordPair implemented. The application creates a word pair object and calls the method for matching with two different strings-one that produces a match and one that doesn't & to show the results of these matches.
Part B.
An application in the same programme but as part B, that reads in the 'word_list.text' ( that is located in the solution folder). This part to be able to check each line.If the line has a word pair(i.e. two strings separated by a '\t') it puts this string into an ArrayList. If the line does NOT have a word pair, the application put that line into a file 'wrong_lines.txt'(that will be located in the solution folder).This application to count the number of lines without word pairs and reports this number to the user & shows all the input lines in a rich text box. If the word list file is not available, the program to produce an error an appropriate message.
Part C
Trying to have this part of the programme to be an application that reads the wordlist, puts the word pairs into an ArrayList of word pair objects, writes the wrong_lines files, reports on faulty pairs, allows the user to ask for a word and attempt the answer, also tells if the user's answer is correct.
Part D.
This to be a combination of Part A, Part B and Part C.
AM NOT SURE IF AM ON THE RIGHT TRACK WITH THE PART OF MY CODE ABOVE.SEEKING ADVICE ON WHAT COULD BE A BETTER WAY OF WRITING THE RELEVANT CODES.

This sounds very much like homework to me...
Anyway, I think you should include a property "Word1" and "Word2" (or something more meaningful - can't tell you from your description) in your WordPair class.
To have more than one WordPair you could use List<WordPair>.
Btw., your rightpair array (which you don't need in WordPair IMO) contains several errors: Should be "blue\tblau" and "yellow\tgelb".
Oh, and please stop shouting.

mav

Hi All,
I am having a ASPX page on whose submission I open a PopUp Window for
sending mails.In the main page I have four hidden variables for
setting the MailTo Mailcc,MailSubject and MailBody fields which I am
getting in my PopUp Window by using
if((document.getElementById("hdnForPOst").value)=="1")
{
document.getElementById("txtTo").value=window.opener.document.getElementById("hdnMailTo").value;
document.getElementById("txtCC").value=window.opener.document.getElementById("hdnMailCC").value;
document.getElementById("txtMailSubject").value=window.opener.document.getElementById("hdnMailSubject").value;
document.getElementById("txtMailBody").value=window.opener.document.getElementById("hdnMailBody").value;
}
hdnForPOst is the variable set for sending mail.
This script I have pasted in a after my controls code.
The problem is that sometimes this code does't execute and I get a
blank popup Window.
I have checked by putting alerts inside script block also.These alerts
also dont execute.It happens only at times and no specific scenario.
Anybody can help please?

Hey Please put this Javascript in a Seperate js file and call this srcipt in your aspx page through src="_ur.js"file and work like that.
First attached it to a default.htm page and see if the scripts works fine then attach the script to your .aspx page.

Strange one for the experts.... I am using windows 2003, visual studio 2005
I can create and use a single instance performance counter without issue...sort of - will explain later.
I am not able to get a multiple instance performance counter to work. Ther performance counter is added but <no instances=""> are shown so I am not able ot select the performance counter to monitor. The code below that adds an instance runs without throwing an error.
The code:
if (!PerformanceCounterCategory.Exists("JUNK"))
{
CounterCreationData ccd = new CounterCreationData("numberOf", "numbers", PerformanceCounterType.NumberOfItems32);
CounterCreationDataCollection ccdc = new CounterCreationDataCollection(new CounterCreationData[] { ccd });
PerformanceCounterCategory cat = PerformanceCounterCategory.Create("JUNK", "junk category", PerformanceCounterCategoryType.MultiInstance, ccdc);
using (PerformanceCounter c = new PerformanceCounter("JUNK", "numberOf", "instance1", false))
{
c.RawValue = 10;
}
}
using (PerformanceCounter c1 = new PerformanceCounter("JUNK", "numberOf", "instance1", false))
{
for (int i = 0; i < 10; i++)
c1.Increment();
}
A single instance performance counter works but not as expected (the above code, but category marked as single instance and the instance not being specified when creating the counter). The counter is added and I can view in perfmon, but it is not until I have the counter added to perfmon that the incrementing is persisted.
Any ideas?
